Kilometer to Micrometer (km to μm)
Convert km to μm — Length converter
Also written as km to um.
One kilometer equals 1000000000 μm, so to convert kilometers to micrometers you multiply the value by 1000000000. A kilometer is larger than a micrometer — going the other way, 1 μm = 1.000000e-9 km. For example, 10 km = 10000000000 μm and 50 km = 50000000000 μm.
